Thank you very much for purchasing Timelime!
No worries, you can start and stop tasks frequently and the times will be accurate.
That's because internally the app stores timings with a millisecond precision. When timings are added up for a chart or any other display/export, the seconds and milliseconds of each timing are considered.
Also, you can display the duration of each timing in hours/minutes/seconds in the "Timings" view. Just select the timing and choose "Get Info" or click on the colored dot to the left of every timing.
